Throughout history, bridges have always been important and valuable structures in their
own right and as part of our infrastructure, allowing faster and easier communication and
transportation for people, livestock and merchandise. This means that by their very nature,
bridges are built in areas where the topography, the ground conditions, or other existing
structures and developments mean that these locations are not suitable for conventional
pathways, roads or railway construction.
Therefore bridges are found in a wide variety of the most challenging and exposed environ-
ments crossing ravines, around mountains, over valleys, lakes, rivers and even seas or
other urban buildings and structures. Due to the seemingly continuous increase in traffic
frequency and design load across our bridge structures, additional stress and strain are also
constantly being imposed on them.
Modern bridges are built predominantly in reinforced concrete and are these are generally
designed with a service life expectancy of more than 100 years. Recent surveys in both
Europe and North America have shown that the majority of our existing bridges already
exhibit some significant degree of degradation and many of them are therefore in need of
substantial and often urgent, repair and refurbishment works.

Refurbishment of Concrete Bridges with Sika Long Lasting, Cost Effective and Sustainable
Durability
Reinforced concrete bridges are designed to maintain their service
and function over long periods of time. During this service life, the
concrete is subjected to many aggressive influences, including vari-
able loading and vibration, extreme weather conditions, the presence
of chlorides in de-icing salts and cycles of freeze and thaw, plus air
borne chlorides in marine environments.
For new bridges, Engineers need to produce concrete that is able
to achieve this long service life. All relevant Codes of Practice and
Standards must be closely followed, including adequate concrete
cover over the steel reinforcement, good compaction and no voids etc.
Many of our existing concrete bridges are not built according to these
latest standards, which is one reason for the damage and deterioration
that results in a significant reduction of their life expectancy.
To reduce maintenance costs, materials should only be applied thathave proven durability, can increase the service life and reduce the
frequency of such maintenance. Sika provides an extensive range
of solutions for the repair, protection and strengthening of concrete
and also steel bridge structures, to ensure that they can meet their
required durability.
Sustainability
In addition to durability, sustainability and responsibility for the envi-
ronment have become an increasingly important component of the
requirements for the refurbishment of bridge structures. Indeed the
environmental impact of any such public works is also an increasingly
important part of every projects pre-contract risk assessment under
the latest regulations.
The responsible use of our limited natural resources is essential for
future generations, therefore the whole bridge refurbishment process
also has to be considered in relation to the selection of refurbishment
materials that sustainable and ecologically harmless so far as is pos-
sible.
This also includes the potential to minimise pollution increasing traffic
delays, power consumption in the materials production, safe waste
and packaging disposal and minimising the use of scarce resources.Sika is striving for a more sustainable environment by optimizing our
logistics, reducing energy consumption, reducing natural resources in
our production processes and by developing innovative, solvent free
refurbishment solutions to limit the release of VOCs (volatile organic
compounds) for example. In addition Sika actively supports many
varied green projects on a global, regional and local basis worldwide,
to create a more sustainable future.

Values from Sika.
Life Cycle Management
Appropriate life cycle costing and management in all areas of bridge
design, construction and management, including the correct mainte-
nance, not only safeguards the owners investment, but also ensures
the safety of the bridge users, maintains the level of its capabilities
and community functions; plus frequently these landmark structures
can also become an important part of a city, region or even a national
heritage.
Life cycle costing and management provides bridge owners with the
best approach to minimising any closure times and increasing the
periods required between scheduled maintenance works, thereby
also achieving the lowest total cost over the full service life of the
structure.
Sika provides bridge owners and their maintenance managers the
right design and planning tools, followed by well designed and proven,complete refurbishment solutions and systems, to considerably in-
crease the time between the necessary maintenance and / or repair
cycles. This is of considerable help in saving not only in the overall
defined life cycle costs, but also in saving the bridge owners and the
bridge users time, the personal costs of delays and closures, plus the
environmental impact of their bridges.

The Exposure of Concrete Bridges
Dynamic and Static Load
Overloading due to increasing traffic loads, inadequate design, damage to the
structure, stress / fatigue failure, earthquake effects, or any other mechanical
impact such as vehicle impact, can all exceed or reduce the load capacity of
the structure
Wide Temperature Variation
By their nature and locations, bridges are subjected to a wide variation of tem-
peratures between day and night / winter and summer conditions, or between
different sides or surfaces of the structure. These frequent cycles result in
thermal stresses and movement in the concrete structure that can also result
in cracks.
Carbon Dioxide
Carbon Dioxide (CO2) reacts with the Calcium Hydroxide (Ca(OH)2) in the pore
liquid of the cement matrix of concrete structures and deposits as calcium
carbonate (CaCO3). This process known as carbonation reduces the protection
of embedded steel reinforcement, when the process reaches the reinforce-
ment bars.
Fire Damage
Fire due to traffic accidents, for example, can result in a reduction of the struc-
tural integrity of any of the concrete elements including the columns, decks or
precast segments etc.
Surface Erosion / Abrasion
Concrete elements submerged in water such as the bridge piers or columns,
are continuously exposed to erosion and abrasion of their surfaces. Damage
occurs from the action of fast flowing water, and the particles of sand or other
solid materials in the water.
Chlorides Ingress
Chlorides come from de-icing salts used in winter, or from salt water in marine
environments. They can penetrate the concrete structure and once they reach
the reinforcement bars, they can locally destroy the passivation film causing
fast pitting corrosion.
Freeze / Thaw Action
The freeze thaw process creates stresses in the concrete matrix due to the
expansion of free water in the capillary pores during freezing conditions; this
can result in scaling of the surface of poor quality concrete. This action is alsogreatly accelerated by the presence of chlorides in the water.
Water Ingress
Water can penetrate naturally through the capillary pore structures of reinforced
concrete. In areas of carbonated concrete, or where there is a high chloride
content on the surface of the steel reinforcing bars, reinforcement corrosion,
cracks or spalling can occur on the surface.

The repair and protection of reinforced concrete bridges must always
be executed according to all relevant local Standards and Regulations.
After a detailed condition survey and root cause analysis, the right
procedures for successful refurbishment can be defined. Standards
Before defining the repair and protection strategy including detailed
refurbishment procedure, the specific bridge project related refurbish-
ment requirements must be considered. These requirements can have
an important influence in determining the correct design, planning and
(such as European Standard EN 1504-9) define Principles and Methods
to be refurbish damaged concrete. Please refer to our Brochure The
Repair and Protection of Reinforced Concrete with Sika for more infor-
mation relating to repair and protection according to EN 1504-9.
General Bridge Refurbishment ProceduresGeneral Bridge Refurbishment Considerations
Concrete bridges are often built
with innovative designs and can
become well known landmarks in
a region. Therefore the aesthetic
considerations can often also play
an important role in the design
and execution of bridge remedial
works.
Remedial work on complex bridge
structures often demands a com-
plete and integrated system buildup.
It is very important that all of the
products used are compatible.
The use of one full range system
supplier with proven compatible
products and systems ensures that
this is achieved.
Remedial works on a bridge
structure can have a significant
cost; hence the frequency of these
works should be as far apart as
possible. Therefore the products
used in bridge remedial works
must provide adequate durability to
extend the frequency to the defined
service life.
The specific site exposure and
environmental conditions, such as
the climate, access and space for
materials application, also signifi-
cantly influences the selection of
the refurbishment concept and/
or the appropriate materials and
application techniques.
To minimise traffic disruption long
periods of remedial works have to
be prevented. Repairs also have to
be done under live traffic loading.
This requires special materials and
only systems which are specifically
tested to be suitable for application
under dynamic load will achieve
the required quality and durability.
Environmental friendly and sus-
tainable materials such as solvent
free products help to safeguard
the environment. These are
increasingly an important require-
ment and in some countries, addi-
tional taxes now have to be paid
for products that release Volatile
Organic Compounds (VOCs).
The time for the bridge or lane clo-
sure has a direct influence on the
cost of remedial works. The choice
for the selection of repair and
protection systems must allow a
fast return to service and therefore
reduce the disruption of traffic to a
minimum.

This significantly influences the
selection of the appropriate refur-
bishment concept and the specific
materials to be used.

Sika Solutions for Concrete Protection
Overview
To improve the performance and durability of reinforced concrete
surfaces on bridge structures, additional protection systems are fre-
quently required, particularly in refurbishment situations. Typical con-
crete protection systems for bridges can be classified as hydrophobic
impregnations, sealing impregnations, surface coatings, or corrosioninhibitors. These are designed for use in different situations or col-
lectively in alternative combinations, to greatly reduce damage to the
concrete surfaces and to stop or significantly reduce the rate of steel
reinforcement corrosion. Thus preventing the even more significant
structural damage, that would otherwise occur.
Requirements
Protection against ingress of water, chloride and carbon dioxide
High resistance against UV radiation
Resistance against frost and wide temperature variations
Sika in Concrete Protection
Sika provides a wide range of tested and well proven concrete protec-
tion systems based on different technologies including hydrophobic
impregnations, impregnations, rigid and elastic surface coatings, plus
surface applied corrosion inhibitors. All of these Sika products and
systems fully comply with various standards and regulations.

Sika Solutions for Steel Corrosion Protection
Overview
Structural steel is also widely used around the world for the construc-
tion of bridges and bridge components including the superstructure,
parapet railings, decks and cables. The corrosion protection of this
steel is therefore essential to increase the durability and sustainability
of the structure. Chlorides and condensed water can accelerate thesteel corrosion process and must be kept away from the steel surfaces.
Requirements
Corrosion protection in accordance with EN ISO 12944
UV and weathering resistance
Coating system service life of 20 25 years to reduce
maintenance / closures
Fulfil high aesthetic demands in appearance
Low VOC emissions
Fast curing / short inter-coat waiting times

Sika Solutions for Structural Bonding Works
Overview
Structural adhesives are used for many bonding applications in new
construction and refurbishment. The bond must allow the transfer of high
loads without deformation and creep.
The main function of structural adhesives is in the bonding of similar or
dissimilar materials together (i.e. concrete to steel, steel to composites etc).Dependent on their design, structural adhesives can not only bond the
elements together, but they can also fulfil additional functions such as
waterproofing, sealing, concrete protection or even vibration dampening.
Requirements
Good creep resistance
Uniform and direct load transmission
Resistant and able to accommodate dynamic loading
Good ageing resistance
Sika in Structural Bonding
Sika has been a pioneer in the use of resin adhesives for structural
bonding of precast concrete elements since the 1960s. Sikas epoxy
adhesives have now been used to bond segmental bridge structures
all around the world. This extensive experience has allowed the devel-
opment of a wide range of additional structural bonding products and
systems for unique applications. In the 1990s Sika also introduced a
complete range of cartridge applied resin anchoring adhesives for
many different applications.
